NUT-LOCK.

SPECIFICATION forming part of Letters Patent N 0. 665,053, dated January1, 1901.

Application filed June 23, 1900. Serial No. 2l 324. (No model.) v

To all whom it may concern: Be it known that I, WALTON GHAPPE BERRY, acitizen of the United States, residing at Rome, in the county of Floydand State of Georgia, have invented a new and useful construction ofNut-Lock, of which the following is a specification.

My invention is an improved construction of nut-lock adapted forsecuring the nuts upon bolts used in connection with rail-joints; but itwill of course be understood that my invention can be applied to otherconstructions wherein it is desired to securely fasten the nut upon itsbolt and prevent accidental displacement by jarring or otherwise.

Another object of the invention is to provide a highly eflicientnut-lock which shall consist of few parts and which can be easilyassembled into operative positions; and with these objects in view theinvention consists in providing a washer with means for rigidlyconnecting it to the fish-plate and having its aperture formed with aseries of ratchet-teeth adapted to be engaged by one end of a split ringlocated within the washer, the bolt being adapted to pass through thesaid washer and split ring, said split ring having projections extendingbeyond the face of the washer and adapted to engage recesses produced inthe inner faces of the nut, so that the nut and ring will move together,and in this man'- ner the nut will be securely held against any rearwardmovement, as it will be impossible for the ring to move, and likewisethe washer.

The invention consists also in certain details of construction andnovelties of combination, all of which will be fully describedhereinafter and pointed out in the claims.

In the drawings forming part of this specification, Figure I is aperspective view showing a bolt passed through a railroad-rail andsurrounded by the washer and locking-ring, the nut being removed. Fig. 2is an inverted perspective view of the nut. Fig. 3 is a detail sectionalview showing the position of the parts when in their locked position.Fig.

4 is a detail perspective view of a washer, and Fig. 5 is a detailperspective view of the ring.

In carrying out my invention I employ a washer A, which is provided withone or more studs A upon the under face thereof, adapted to engagerecesses produced in the face of the fish-plate. The opening of thiswasher A is made somewhat larger than the diameter of the bolt and has aseries of ratchet serrations or teeth A produced thereon, and arrangedWithin the washer is a split steel ring B, one end being shaped toengage the ratchetteeth in the Washer, so that the said ring can bemoved around within the washer in one direction, but will be preventedfrom movingin the reverse direction by the engagement of the pawl end Bwith the ratchet-teeth of the washer. This ring B is also provided withears or lugs B extending beyond the face of the Washer-A, said lugs orears being adapted to rest in recesses 0 produced in the inner face ofthe nut C upon the opposite sides of the central threaded opening 0.When the nut is turned down sufficiently to bring the lugs or extensionsB into therecess G the ring will then be caused to turn within thewasher as the nut is screwed down tight upon the bolt, the pawl end B ofthe ring slipping over the ratchet-teeth. During this operation thewasher is of course held fixed, and likewise the bolt, so that the nutcan be screwed tight, and when once secured it will be impossible forthe said nut to become loose by being turned backwardly, inasmuch as thesaid nut is held in place by means of the ring and the ring is preventedfrom moving by the engagement of the pawl end thereof with theratchetteeth of the washer. Whenever it is desired to remove the nut,the bolt should be turned from the reverse end.

It will thus be seen that I provide an exceedingly simple and efficientconstruction of nut-lock which will securely hold the nut upon the bolt,and it will also be noted that these objects are obtained by means ofvery few parts, which can be cheaply and easily constructed and readilyarranged in their operative positions.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is

1. In a nut-lock, the combination with a Washer, having ratchet-teetharranged within the opening, a locking-ring adapted to engage a splitring having a pawl at one end and carrying one or more lugs or earsextending beyond the washer, said split ring beingarranged Within theratchet-faced opening of the Washer, and the nut having one or morerecesses adapted to receive the lug or lugs carried by the split ring,substantially as and for the purpose described.

the teeth of the Washer and provided with means for engaging the nut,substantially as described.

2. In a nut-1ock, the combination with a Washer having ratchet-teethproduced in the central opening, of the split ring arranged Within theWasher and adapted to engage the ratchet-teeth, and having one or morelugs or extensions adapted To engage a recess in the nut, substantiallyas described.

3. In a nut-lock, the combination with the washer having the internalratchet-teeth, of 1
